UNITED STATES PATENT OFFICE THEODORE C. mm OF CHICAGO, ILLINOIS,ASSIGNOB TO AUTOMATIC ELECTRIC INC,

OF CHICAGO, ILLINOIS, A CORPORATION 01' DELAWARE Tm! HOOD-DIN G DEVICEApplication fled August 18, 1937. Serial No. 814,088.

My invention relates in general to recording devices, and moreparticularly to those devices from which a record may be obtained inpermanent record form.

The main feature of m invention is the provision of a time recordingclock which is accurate and reliable in its performance, which willclearly print a very complete record and which may easily be adapted toa great variety of uses.

This feature, as well as others not particularly mentioned, will be morefully hereinafter described in the following description.

For a more complete and better understanding of my invention, referencemay be had to the accompanying drawings in which:-

Fig. 1 is a perspective View of the time recording clock with enough ofthe casing cut away to show these features which constitute a part of myinvention.

Fig.9 is a perspective view of the stamping and recording mechanismwhich also constitutes a part of my invention and which is, in thisparticular case, designed for use with the clock shown in Fig. 1.

Fig. 3 is a rear view of the stamping and recording mechanism with aportion of the rear mounting plate cut away so that the construction ofthe mechanism may be more readily seen.

In these figures, like parts are denoted by like reference characters.

The clock in Fig. 1 may be any suitable one which is arranged forrecordin the time and date. In this particular case I ave used astandard recording clock manufactured by the Follett Time RecordingCompany, of Newark, New Jersey. This clock consists of a regular springdrivenfclock mechanism adapted to operate indicating wheels which, whenplaced'in correct stain ing position, will indicate the time and ate. Tothis standard recording clock I have added new features, or elements, towork simultaneously with the mechanism of the standard clock to givecertain other indications.

. To this clock, I have also added the mechanism shown in Figs. 2 and 3,which consists of electrically operated means for stam ing and recordingthe indications of the c ock in a permanent record form.

Before proceeding with a detailed description and operation of the timerecording clock with the added features or elements, it might be well tostate that the complete recording mechanism assembly may be put toinnumerable uses, especially in supervisory systems and in remotecontrol systems. One

typical use to which the product of my invention may be put is thatshown and described in the application of Harry E. ggrzshey, Serial N 0.214,060, filed August 19, Mr. Hershey has provided means whereby myinvention may be used to supervise the operations of a plurality ofswitching devices such as circuit breakers or the like. In rovidingthese means, he has employed a se ecting mechanism which operates inresponse to the operation of any one of the switching devices, to selectthat device and connect itto the recorder so that a record may be madeof the operation. The recorder is arranged to operate in synchronismwith the selecting mechanism as is explained in Mr. Hersheys applicationand which will be explained herein a little further on in thedescription.

Referring now to Fig. 1 more in detail, it will be seen that thecomplete clock has a casing consisting of a base, 1, and side walls, 2.The front wall is in the form of a door hinged to the base and adaptedto swing forward and downward. On base 1 is mounted the clock mechanismM, which has, besides the regular spring movement, indicating Wheels 3,4, 5, 6 and 7 which are controlled by the regular clock mechanism andindicate the month, day of. the month, the hour the minute of the hour,and the portion of the day, AM or PM, respectively. The face of theclock is visible through a round opening in the front side of the casingand is protected by a glass crystal.

As the clock works so far described are not a part of my invention, itis thought that a further description of them is unnecessary. To themechanism as before described I have added the indicating disc 8 and theindicating plate 9, both of which are rotatably' mounted on the shaft10. Firmly attached to the disc 8 and concentric with it, is a ratchetwheel 11 which is for the purpose of rotating disc 8. The periphery ofdisc 8 is marke with numerals 1-25, inclusive, and the ratchet wheel 11has 25 teeth. I have also added the rela 12 whose armature 13 has a longprojecting arm with a pawl 14 hinged at 15, the hinging portionconsisting of two pro ect ing ears on the end of the pawl 14. A 0011spring about the hinge-pin 15 is adapted to hold the pawl 14 inengagement with the teeth of ratchet wheel 11. The stroke of armature 13is so adjusted that with each deenergization of relay 12, the disc 8 isrotated one step in a clockwise direction about the shaft 10. The relay12 is mounted on the middle supporting plate 16. Indicating plate 9 isof t e general shape shown in F ig. 1 and it has a projecting arm 17formed integral with it and on the direct opposite side of the shaft 10.In the plate 9 is a slot 18, the sides of which are arcs of circlesconcentric with the center of rotation of plate 9. A pin 19 is mountedin the front supporting plate 16 and is so located as to fit in the slot18. This pin 19 acts as both a forward and backward stop to the movementof plate 9. To operate the plate 9, I have added the relay 20 with itsarmature 21 pivoted at 22. A connecting rod 23 joins the projecting arm17 to the armature 21 at pivot points 24 and 25. A tension spring 26keeps the armature 21 in its inoperative position, that shown in thedrawlngs, when relay 20 is deenergized. When relay 20 is energized itattracts its armature 21. The motion of armature 21 is transmitted toarm 17 and plate 9 through the connecting rod 23, thus rotating 9 and 17in a counterclockwise direction about shaft 10.

On the periphery of plate 9, there is raised marking X which is solocated that it is in alignment with the indications on indicating discs3,4, 5, 6, 7 and 8 in the stamping position when the armature 21 is inits operated position.

As I said previously, the recorder is operated in synchronism with theselecting mechanism of Mr. Hersheys invention. This is accomplished byoperating relay 12 simultaneously with the motor magnet of the selectingmechanism which may be a well known forward-hunting, rotary-type switch.Thus it can be understood that when relay 12 and the motor magnet areoperated together, the indicating disc controlled by relay 12 and thewipers controlled by the motor magnet will be moving together. Thenumerals on the periphery of indicating disc 8 are so positioned thatwhen the wipers of the selecting mechanism are advanced to the first setof bank contacts, the numeral 1 will be in the stamping position.Numeral 2 will appear in the stamping position when the wipers have beenstepped to the second sets of bank contacts, and so on accordin to thenumber of sets of bank contacts to w ich the wipers have access. Theswitching devices are connected to the bank contacts of the selectingmechanism in an orderly fashion so that device #1 is connected to thefirst set of contacts, device #2 to the second set of contacts, and soon. Thus the numeral on the indicating disc will denote the number ofthe device so ected by the selecting mechanism.

Relay 20 is so connected that when the switching device is in oneposition it will energize and when the device is in another position itwill not energize. Thus the presence or absence of the mark X willdenote the position of the switching device. Thus a complete record fromthe recorder will indicate the time and date of the operation of theswitching device the number of the device operating, and the position towhich it has moved.

The stamping and recording mechanism shown in Figs. 2 and 3 is mountedon the top plates 27 which acts as the cover of the clock casing. On theunderside of this top plate are mounted 2 rollers 28 and 29 betweenwhich is stretched an inked tape. When the top plate is in position thisinked tape will 3e stretched across the tops of the indicating 1scs.

In the center of the plate 27 is mounted a bracket 30 which is adaptedto support the solenoid coil mounting frame 31 and solenoid coil 57.Through the hollow core of solenoid coil 31 extends the octagonalplunger 32. An octagonal plunger is used so that the rubbing surfacewill be reduced to a minimum. On the lower end of the plunger isfastened a stamping block which is not visible in the drawings. Thisstamping block is rectangular in shape and is long enough to cover allof the indicating discs and plates. There is a rectangular hole in thetop plate 27 throu h which the stamping block passes when tire plungeris operated. Around the extending portion of plunger 32 is a spiralrestoring sprin 33 which is held in place between the top 0 coil 31 andthe large, flat-headed screw 34 screwed into the top end of plunger 32.

Close and parallel to the rear edge of top plate 27, there is mounted avertical mounting plate 35. On this plate 35 are mounted two largespools 36 and 37 by means of large bolts not visible in the drawings.These spools carry the paper upon which is stamped the indications ofthe clock mechanism. The paper unrolls from spool 36, passes under guidebars, not visible, over the hole in top plate 27 and under stampingblock on end of plunger 32, and is wound onto spool 37.

To operate the spools, I have attached to the rear side of spool 37, aratchet wheel 38 and provided the H shaped member 39 which is centrallypivoted on pivot pin 40 which is fastened in mounting plate 35. Theguide engage the teeth of ratchet wheel 38.

pins 41 and 42 are fastened near the ends of the opposite sides of themember 39. Pin 41 rides on the head of screw 34. The ur ose of pin 42will be described hereinatter. About the pivot pin 40 is wound a spring43 so that when plunger 32 is down member 39 will be rotated in acounter-clockwise direction as far as the plunger will allow it torotate. ward under the pressure of spring 33, 39 will be rotated in theopposite direction against the tension of spring 43. Pivoted .on theaxle of spool 37 is pawl bearing member 44 which has the. two radialarms 45 and 46 located directly opposite each other, and the radial arm47 located at an angle of 90 degrees to arms 45 and 46 but lying in thesame plane. Pawl 48 is centrally pivoted, with respect to itself and arm45, at 50. One end of pawl 48 is bent towards the center of rotation ofthe pawl bearing member 44 so 213120 e pawl is held inengagement byspring 52. Pawl 49 is similar to pawl 48, being pivoted at 51 and beingheld into engagement with teeth of ratchet wheel 38 by spring 56. Pawls48 and 49 are so arranged that'when one is in engagement, the other willbe Just half-way between two. teeth of the ratchet wheel. These pawlsalternate in engaging the teeth. Thus a more uniform amount of rotationof spool 37 may be secured. The connecting rod 53, pivotally fastened to39 at 54 on the opposite side of the pivot pin 40 from the pins 41 and42, and to arm 47, at 55, translates the motion of 39 to pawl-bearingmember 44 and thus to arms 45 and 46. Thus it will be seen, that whenplunger 32 is pulled down, 39 will rotate in a counterclockwisedirection looking at Fig. 2, imparting a rotary movement to 44 in aclockwise direction and when plunger 32 returns to normal it pressesagainst pin 41 and rotates 39 in a clockwise direction. 39 turning inthis direction will impart an opposite motion to 44, 45, and 46, whichthrough the action of either one of the pawls 48 or 49, will rotatespool 37 in a counter-clockwise direction. This rotation of spool 37will wind paper upon itself and unroll it from spool 36. Holding springs58 and 59 are fastened to the mounting plate 35 and enga e the teeth ofratchet wheel 38 to prevent bac ward rotation of spool 37.

It can readily be understood that for one complete stroke of plun er 32,the length of the paper which woul pass the stam ing block would varyaccording to the size 0 the roll on spool 37 When the roll of paper onspool 37 is very small, a turn of that spool governed by the stroke ofplunger 32 will draw very little of the paper past the stamping block,and one record stamped on the paper is liable to be stamped almostdirectly on top of the previously stamped record.

Thus when the plunger returns up- Therefore, to overcome this objectionI have provided means which will insure that the same length of paperwill pass the stamping block after each stamping so that all stampingson the roll will be evenly spaced.

This means, or paper controlling mechanism, consists of a rocker armarrangement to control the movement of an adjustable stop for the member39. The rocker consists of the two rocker arms 60 which are rotatablymounted-on opposite sides of the bracket 30 by pivot pins 61. Theopposite ends of the roc er arms 60 are connected together by a rod 62on whichis a roller 63. The rocker arms are so spaced as to fit inbetween the two sides of the spool 37 and they are so placed and shapedas to allow the roller 63 to roll upon the roll of paper on spool 37. Atension spring, not shown, holds the roller 63 against the surface ofthe paper on spool 37. A triangular shaped member 64 is pivoted at itsapex on in the end 0 bracket30. The pivot pin 65 is located so as to liein the same vertical plane in which the pins 41 and 42 lie. The side ofthe triangular shaped member, opposite the apex, is an eccentric, thepurpose of which wil be explained a little later. Trr

pivot pin 65 which is mounted a angular shaped member 64 is connected torocker arms 60 by means of connecting rod 66 at pivot points 67 and 68.

The explanation to follow will be directed entirely to Fig. 3 so thatdirections of rotation will not be mistaken for those in the previousexplanation.

As previously stated, the roller 63 rides upon the roll of paper onspool 37 It can be readily understood that as the size of the roll ofpaper on spool 37 increases, the rocker arms 60 will be rotated in aclockwise direction about pivot pins 61. This rotation of arms 60 willimpart a clockwise direction of rotation to triangular shaped member 64about pivot 65, which motion is translated by connecting rod 66. Theposition of 64 when the roll of paper on spool 37 is small isrepresented by the dotted-line triangle.

The manner in which this mechanism controls the amount of paper to bewound on spool 37, or to be drawn past the stamping block, will now beexplained.

The pin 42 mounted on member 39, stops against the eccentric side. ofthe triangular shaped member 64 when the plunger 32 has moved downward.Thus it can be seen that the amount of rotation of 39 is controlled bymember 64, the amount of rotation decreas ing as 64 is rotated in aclockwise direction. The eccentric side of 64 is so shaped that incontrolling the amount of rotation of member 39, it allows only the sameamount of paper to be wound upon spool 37 upon each operation of thestamping mechanism since, as previously explained, the rotation ofmember 39 is imparted to spool 37 by means of the pawls and connectingmembers. When the eccentrio is nearest to 39, the allowable rotation of39 is at a minimum, but that rotation is suflicient to allow pawls 48and 49 to be advanced a step, or one. full tooth.

As there are modifications and ada tions which can be made by oneskilled in t e art without departing from the scope of the invention, itis not my invention to limit my invention to the present disclosure.

Having thus described my invention, what I consider new and desire tohave protected by Letters Patent will be pointed out in the ap endedclaims.
